Description

Technical Field

[0001] The utility model relates to a vehicle-mounted intelligent side window defogger system, belonging to the field of automobile electronic control. Background Art

[0002] At present, the current automobile side window defog technology has a certain lag, and it mainly relies on the driver to manually discover the side window fogging, and then perform the defog function by manually wiping it or the air conditioning heating function. This type of side window defog method requires the driver to observe the side window first, and then perform additional manual defog operation, which is bound to affect the driver's attention. In addition, the side window defog has a lag. When the driver discovers that the side window is foggy, it is often too late to perform the defog operation, which affects the driver's observation of the side road conditions and the left and right rearview mirrors. This is very dangerous during the driving process of the car. Summary of the invention

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a vehicle-mounted intelligent side window defog system to realize an automatic defog function.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] An on-vehicle intelligent side window defog system comprises: a side window condensation detection module, a feedback information processing module and a side window defog module;

[0006] The side window fogging detection module is embedded in the side window glass interlayer, and includes a capacitance detection area, an anti-false touch detection area and a shielding area. The capacitance detection area is a closed silver paste line, the anti-false touch detection area is arranged in the closed area of ​​the silver paste line, and the shielding area is arranged around the silver paste line and the anti-false touch detection area.

[0007] The capacitance detection area, the anti-mistouch detection area and the shielding area are all connected to the feedback information processing module, and the feedback information processing module is connected to the side window defogger module.

[0008] Furthermore, the feedback information processing module includes a feedback information processing module, an MCU module and a communication module, the input end of the feedback information processing module is connected to the capacitance detection area, the anti-mistouch detection area and the shielding area, the output end of the feedback information processing module is connected to the IO port of the MCU module, the input end of the communication module is connected to the IO port of the MCU module, and the output end of the communication module is connected to the side window defogger module.

[0009] Furthermore, the feedback information processing module includes a feedback information processing chip, and the model of the feedback information processing chip is CY8C4025.

[0010] Furthermore, the MCU module includes an MCU chip, and the model of the MCU chip is FS32K144HAT0MLHT.

[0011] Furthermore, the communication module includes a CAN transceiver, and the model of the CAN transceiver is TCAN1044.

[0012] By adopting the above technical scheme, the utility model uses capacitance detection sensing technology to treat the side window glass as the area to be detected. When fog beads condense on the glass surface, the dielectric constant of the side window glass will also change accordingly. As long as the fog beads on the side window glass are detected to be within the range required for defogging, the feedback information processing module will automatically start the side window defogging module, thereby realizing the intelligent automatic defogging function of the side window.

[0016] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0017] like Figure 1 As shown, this embodiment provides a vehicle-mounted intelligent side window defogger system, which includes: a side window condensation detection module, a feedback information processing module and a side window defogger module.

[0018] The side window fogging detection module is embedded in the side window glass interlayer. The side window fogging detection module includes a capacitance detection area 1, an anti-false touch detection area 2 and a shielding area 3. The capacitance detection area 1 is a closed silver paste line, the anti-false touch detection area 2 is set in the closed area of ​​the silver paste line, and the shielding area 3 is set around the silver paste line and the anti-false touch detection area 2. The capacitance detection area 1, the anti-false touch detection area 2 and the shielding area 3 are all connected to the feedback information processing module, and the feedback information processing module is connected to the side window defogger module.

[0019] By arranging a closed silver paste line between the inner interlayers of the side window glass as the capacitance detection area 1, when fog condenses on the side window glass, the liquid is charged, which will cause a change in the dielectric constant. The change in the dielectric constant is converted into a change in capacitance, which is fed back to the information processing module in the form of current. The anti-mistaken touch detection area 2 is a plurality of circular areas made of silver paste. The distance from the edge of the circular area to the silver paste line is less than the width of a human finger. If a person touches the closed area of ​​the silver paste line, it can be identified by the anti-mistaken touch detection area 2 and the mis-touch action can be shielded. A shielding area 3 is arranged around the silver paste line and the anti-mistaken touch detection area 2. The shielding area 3 is composed of a silk screen made of silver paste for signal shielding, such as Figure 3 As shown, A is the shielding waveform and B is the capacitance detection waveform.

[0020] like Figure 2 As shown, the feedback information processing module of this embodiment includes a feedback information processing module, an MCU module and a communication module. The input end of the feedback information processing module is connected to the capacitance detection area 1, the anti-mistouch detection area 2 and the shielding area 3, the output end of the feedback information processing module is connected to the IO port of the MCU module, the input end of the communication module is connected to the IO port of the MCU module, and the output end of the communication module is connected to the side window defogger module. Among them, the feedback information processing module includes a feedback information processing chip, and the model of the feedback information processing chip of this embodiment is CY8C4025. The MCU module includes an MCU chip, and the model of the MCU chip of this embodiment is FS32K144HAT0MLHT. The communication module includes a CAN transceiver, and the model of the CAN transceiver of this embodiment is TCAN1044.

[0021] The feedback information processing chip CY8C4025 receives the detection signal transmitted from the capacitance detection area 1, and compares the detection signal with the data set to be defogged stored in the vehicle cloud server. When the detection signal data reaches the data set range, it is concluded that the side window begins to condense fog, and the MCU module issues a corresponding control instruction to control the side window defog module to perform the defog operation. The side window defog module of this embodiment is a vehicle air conditioning outlet device, and the vehicle air conditioning heats and blows the glass to perform the defog operation on the side window glass.

[0022] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
